** About the Team
** The Data Platform and Observability team is based in Pleasanton, CA;
Boston, MA; and Dublin, Ireland. We enable real-time insight across Workday's platforms, infrastructure, and applications — including the AI agents and automated workflows that are becoming part of how those applications run. Our focus is building a large-scale distributed data and observability platform that keeps critical Workday services, and the AI-powered capabilities layered on top of them, fast, reliable, and trustworthy in production.
We handle hundreds of terabytes of data and billions of messages produced daily across Workday's applications and underlying services, powering a platform that tracks over 2 billion time-series in production. We're also modernizing how we do observability itself — bringing AI-driven approaches like anomaly detection, intelligent alerting, and automated root-cause analysis into the platform, so our systems get smarter about surfacing problems before they become incidents.

If you enjoy writing efficient software, tuning and scaling large distributed systems, and applying AI to make observability itself sharper, you'll enjoy working with us.
Do you want to solve interesting challenges at massive scale, across private and public cloud, for 4,000+ global customers — while helping define what "observability" means for the next generation of AI-driven products? Do you want to work alongside world-class engineers building the platforms that make that possible?
If so, we should talk.
** About the Role
** The Data Platform and Observability team is hiring a Senior or Mid-Level Software Engineer. We have a hybrid schedule — you'll collaborate with Workmates in the office while having the flexibility to work up to 50% remote.
* Design, build, and improve critical observability services:
Monitoring, Logging, Alerting, and Tracing.

* Build data capture and collection services using the latest technologies across multiple infrastructure types (Kubernetes, Docker, Open Stack, bare metal, etc.).
* Design and develop core software modules for real-time and batch data processing.
* Build metrics ingestion pipelines, alert definitions, and automation for dashboard lifecycle management.
* Instrument AI-powered and automated workflows for performance, cost, and quality, including multi-step processes and tool/service…
